I wanted to reduce the size of the files on an mp3 CD audio book, from 92 Kbps stereo to 32 kbps mono, so they would fit on my mp3 player. My first try, I missed the preload option in FFConvert. The minimum bitrate FFConvert would allow was 64 kbps, so that's what I chose for the test.

FFconvert didn't have any problem with spaces in the directory names, but it failed to convert the files to mono or to 64 kbps. I'm pretty sure I set up the GUI correctly, but maybe not.

When that didn't work, I took another look at the GUI and discovered the preload section had an mp3 32 kbps mono option. This also had no problem with spaces in the directories, but it skipped converting three of the 91 mp3 files on the CD. All three files play in Gxine from the CD, but when I tell FFConvert to convert them, it says there is no video or audio stream to convert.

The audio quality of the converted 32 kbps mp3 files is perfectly adequate for my purpose. They sometimes sound slightly rough, like someone speaking through a fan, but if the book is good I get into it and I don't notice the roughness.

For the OGG preset your need to change the file format parameter to "ogg" from "OGG"._________________adobe flash is rubbish!

Here is the SHA1 checksum of the ffmpeg20100408-0.9.pet I am using: eb063a38ebfc9f2667157423e9b15d3fa0a4fd71

An other problem is ffconvert still can't cope with paths with spaces. A feature I would love/badly need is for metadata to be copied across between converted files. FFmpeg has this option:

Code:

-map_meta_data outfile:infile set meta data information of outfile from infile

But I can't get it to work at all. I have tried it with flac to ogg, flac to acc (yuck) flac to mp3 (yuck) with all possible methods I can think of and it still refuses to do its job . So the only way I can think to do it, Is by using the

Code:

-metadata string=string add metadata

option to add the metadata with the "-y" option to get the meta data. Here is how far I have got with writing a script to do it:

The version of FFmpeg that Puppy came with before the 5 series does not have the "-metadata" option. So I used the right options for that version. Hence the "if" statement._________________adobe flash is rubbish!
